No hard right turn issues. TPS and IAC were changed out less than a year ago. Maybe when I replace these plugs tomorrow (showed heavy signs of detination) from platinum to champion copper. it'll feel better. still have no clue where to gap these F'n plugs though

lol... your gonna pi$$ed and happy both

it'll fix it

my issue was it ran hard til 3000... from 3000-4500 it stumbled like it was on 5 cylinders, but only had the issue in 1st gear (most load maybe ??) thenw after 4500 it picked up again

i changed: cap,rotor,fp reg, fuel pump, coil

all to no avail. swapped those plugs and gapped them down..... golden

Put the new plugs in. NOW THE DAM THING FARTS OUT @ 2500. But only sometimes. I destroyed my MAF earlier this year. I guess I finally need to replace it.

wtf? you sure you didnt swap a plug wire ? and are u sure each one "snapped" all the way on ?

id reset the puter by unplugging the batt for 20 minutes. check all that stuff over, reconnect it, check timing and make sure the wires arent arcing on anything
